Hit and run

Hit and run, also known as kiting, is a trick used for fighting monsters which may have powerful melee attacks but are slower than the player, such as mimics, black puddings, and rothes. This tactic is known as hack-and-back in Angband circles.

How it works

NOTE: In 3.6.0 the monster speed mechanics have changed.[1] Instead of accumulating movement points, monsters randomly get an extra turn with probability proportional to their extra movement. E.g., a mimic (speed 3) has a 25% chance of moving each turn, and a killer bee (speed 18) has a 50% chance of moving a second time each turn, irrespective of preceding movement. Thus, you should always assume that the monster's speed is rounded up to 12, making the strategy below only useful if you are very fast or riding.

A monster can use each turn it gets for either movement or attacking you, but not both. For example, if a monster moves at least twice as slowly as the player, it cannot melee you the turn immediately after it moves, and you can safely attack it on that turn.

All slow monsters have to pause a turn at a predictable rhythm, e. g. always after three movements. You can hit such a monster as often as you wish without a single counterattack: You start stepping back immediately after you attack it, and then you attack it only when it moves adjacent to you right before its scheduled pause. You can use hit and run tactics for all of your attack types: melee, pounding, missiles, and spells.

Intrinsic and extrinsic speed are erratic, and you should act as if you have the minimum possible speed. When fast (i.e. wand of speed monster, "You feel quick!", etc.) you get a 2 in 3 chance of +6 speed, and should act as if you are still moving at normal speed, rather than acting like you have a speed of 16, to avoid getting hit the 1/3 of the time your speed bonus doesn't apply. When you are very fast (speed boots), however, you are guaranteed at least 18 speed (and a 1 in 3 chance of another +6), and can successfully defeat anything slower than 18 while never getting hit. In both of these cases, when you get your extra move, you should rest and wait for the monster to move adjacent to you and then start the rhythm over again. Note that extra speed from polymorphing yourself or riding is always reliable, so an unburdened player riding a warhorse should count his speed as 24.

If your movement rate is at least double the monster's movement rate, take the ratio of the monster's rate divided by your movement rate, and round up to the nearest point on this table:

If your movement rate is less than double the monster's movement rate, take the ratio of your rate divided by the monster's rate, and round up to the nearest point on this table:

Examples:

An unburdened player without will move at 12, and a gnome will move at 6. Since 6/12 = 1/2 = 50%, the hit-and-run rhythm against a gnome will be move once, hit once; move once, hit once; etc.

An unburdened player with speed boots will move at a minimum speed of 18, and a black pudding will move at 6. Since 6/18 = 1/3, the hit-and-run rhythm against a black pudding will be move once, hit twice; move once, hit twice; etc. However, 1/3 of the time, you will move at 24, in which case you will end up moving twice in a row. In this case, simply rest until the black pudding moves adjacent to you and start again.

A burdened player without will move at 9, and a chickatrice will move at 4. Since 4/9 = 44.4%, round up to 50% and follow the same rhythm as the gnome

A player riding a horse will move at 20, and a leocrotta will move at 18. Since 18/20 = 9/10, this player can safely hit the leocrotta after every nine moves. In practice, it is difficult to hit-and-run at this speed unless you have a loop to move around and there are no other monsters nearby. If the player were riding a warhorse (speed 24), 18/24 = 3/4, so the player could hit after every three moves.

Dangers

Hit and run is most likely to be successful if the monster in question is the only monster nearby. It's best to close doors or block off other exits (e.g. dropping an item on an Elbereth square or using a scroll of earth) to avoid having other foes intrude on your hit and run session. Hit and run can also be dangerous when facing a creature that has a projectile attack.

One common tactic is to hit and run in a circle, looping around a set of hallways, a boulder, or a cave formation that allows maneuverability all the way around. When doing this, watch out for monsters that could block the path ahead of you. Using hit and run on puddings when using an iron weapon is not totally safe since if the monster divides, that extra monster could appear adjacent to you and block the way or attack the next turn. For example:

There is now nowhere to go to escape the black pudding on your next move. If you are low on HP, you might want to consider using an escape item, or as a last resort, engraving Elbereth in the dust to get away.
